We divide 79110621 by 229
The aim is to understand the frequency of 229 in 79110621.

Step 1:
When dividing 7 by 229, we get 0 with a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Grab the next digit (9) from the dividend, add it to 7, then carry on: 79 / 229

On to step 2:
229 can be fit into 79 0 times, resulting in a remainder of 79.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 79 and we're left with 79.
Grab the next digit (1) from the dividend, add it to 79, then carry on: 791 / 229

On to step 3:
The number 229 fits into 791 3 times, leaving a remainder of 104.
Use 3 as the next digit of our solution. 
Result so far: 3.0
If we take 687 away from 791, we end up with 104.
Bring next digit (1) of the dividend behind the 104 and repeat the process: 1041 / 229

Step 4:
When dividing 1041 by 229, we get 4 with a remainder of 125.
Write down 4 as next digit of the result. 
Result so far: 34.0
The remainder is 125 after subtracting 916 from 1041.
Include the next digit (0) from the dividend after 125, then repeat: 1250 / 229

Going ahead to step 5:
229 goes into 1250 5 times with a remainder of 105.
The number 5 becomes the next digit in our result. 
Result so far: 345.0
If we take 1145 away from 1250, we end up with 105.
Take the next digit (6) from the dividend and append it to 105, then repeat: 1056 / 229

On to step 6:
When dividing 1056 by 229, we get 4 with a remainder of 140.
The number 4 becomes the next digit in our result. 
Result so far: 3454.0
Deduct 916 from 1056 and we're left with 140.
Take the next digit (2) from the dividend and append it to 140, then repeat: 1402 / 229

Step 7:
The number 229 fits into 1402 6 times, leaving a remainder of 28.
Use 6 as the next digit of our solution. 
Result so far: 34546.0
Subtracting 1374 from 1402 leaves us with 28.
Bring next digit (1) of the dividend behind the 28 and repeat the process: 281 / 229

Step 8:
229 can be fit into 281 1 times, resulting in a remainder of 52.
The number 1 becomes the next digit in our result. 
Result so far: 345461.0
Deduct 229 from 281 and we're left with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Going ahead to step 9:
229 goes into 520 2 times with a remainder of 62.
Put 2 as the next digit of the answer. 
Result so far: 345461.2
If we take 458 away from 520, we end up with 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Step 10:
229 goes into 620 2 times with a remainder of 162.
The next digit of our result is 2. 
Result so far: 345461.22
If we take 458 away from 620, we end up with 162.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1620, and continue the process.

The final outcome is 345461.22, with a leftover of 0.162.
